This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.

中文摘要：本课题是在合作首次发展了氧化物薄膜原子尺度层状外延生长光学原位实时探测方法的基础上立项的，三年来，我们充分发挥双方的优势和特点，圆满完成了课题的设想和计划。1、在物理所建立了一套先进的光反射差法装置，编写了计算机系统的数据采集程序，实现了两路光学信号和RHEED数据的同步采集和显示。2、用激光分子束外延在SrTiO3基底上生长SrNb0.1Ti0.9O3薄膜，首次观测到连续外延几百个原胞层，周期振荡的光反射差实部和虚部信号，证明了光反射差法是一种能原位实时探测与监控薄膜层状外延生长的好方法。3、首次验证了通过对生长表面原子或分子台阶密度的响应，光反射差法可用于原位实时监测在连续生长条件下薄膜的层式生长模式。4、通过唯象理论的研究，证明光反射差信号由三项组成，第一项只与薄膜的平均厚度和宏观光学电介质常数有关；第二项与分子台阶面覆盖度和台阶面上分子层的光学电介质常数有关；第三项与台阶边缘的覆盖度成正比，并和在台阶边缘的分子的有效光学介电常数有关。

Some scientists now say GMT should be replaced by International Atomic Time — computed outside Paris — because new technologies have allowed atomic time to tick away with down-to-the-nanosecond accuracy.

现在有些科学家说，应该用在巴黎近郊1家科学机构）计算出来的「国际原子时间」取代「格林威治标准时间」，因新的技术能使原子时计达到以奈米秒计时的准确程度。

The mechanism studies on the atomic oxygen effects over surface materials become rather difficult due to the fact that the interaction, stemming from a highly complex environment in LEO, where the atomic oxygen are equipping with high translational kinetic energy and strong oxidizing characteristics, may induce complicated physico-chemical processes.

然而，由于空间环境高度复杂，以及环境中原子氧具有高平动能和高度活泼的化学特性，空间材料的原子氧效应呈现复杂的物理化学过程，给该效应的机理性研究带来严重困难。

3At%. Based on the measurement of the grain size, phase contents and their composition, the composition of the trinary interface phase was determined to be 〓, with the thickness of interface phase about 1. 3nm, corresponding to 4～5 atomic layers, and with a lower atomic density as well as a high degree of disorder. In the case, the obtained nano-structure remains stable, unchanged against the continued electropulsing.
